they are plugging a wall at the canal, thus the lake. not the river.

You are, of course, correct. In my mind, I was referring to the flowing of the water between the canal and the city as a river - obviously I did not make that clear.

Pete, I am saving your reply on my desktop to remind myself that even a blind pig finds an acorn. Thanks! ;)
